 Justification is a legal term, is a word used in the Bible to refer to anyone who is accepted in the sight of God as righteous. Justification is a legal term, it's a forensic term that refers to a single act or a declaration by the judge, by God. In justification, a sinner is declared to be righteous. But considering the justice of God, the holiness of God, how can a holy God declare a sinful man to be righteous? How can a sinful man be declared just? Does God just arbitrarily sweep sin under the rug? No. No God declares a sinful man to be righteous or just on the basis of the work of Jesus Christ as a substitute for his people.
